Under the old regime, the ATO discovered unpaid super months or years after the fact, usually from an employee complaint. Under Payday Super, the discovery mechanism is your own payroll software. Every pay event lodged through Single Touch Payroll now reports qualifying earnings and the superannuation liability attached to it, while funds report the contributions they actually receive, and must allocate or return every contribution within 3 business days. The ATO matches the two streams continuously. The reporting layer is the enforcement layer now, and this guide covers exactly what flows where, what employers must get right in their STP data, and how to run the reconciliation rhythm the new visibility demands.
Published: July 2026
Understand the design and the strategic conclusion is immediate: there is no version of Payday Super compliance that survives inaccurate reporting, and no version of non-compliance the reporting does not surface. For the broader regime, see our Payday Super guide and the Single Touch Payroll complete guide. Day-to-day execution sits in finance services. Official STP and Payday Super detail sits on the ATO STP pages and ATO Payday Super pages.
Four disciplines carry the reporting obligation.
A payroll codes $8,000 of monthly commissions as non-QE. STP reports lower liability than the law requires. Funds receive only the understated super. The ATO match may not flag a gap between reported liability and receipts, because both are low, but the employee and any later review will. When corrected, the business faces historical shortfall on the true QE plus a record that under-reported. Under-reporting is not a clever way to hide; it is a second problem stacked on the first.
The fund-side deadline changes the texture of error handling in the employer’s favour, but only for employers who are watching.
Under the old settings, a contribution rejected for a bad member number could take weeks to surface, by which time several more pay cycles had bounced against the same stale detail. Now a contribution that cannot be allocated must come back within 3 business days. Rejections are fast, visible and early, arriving while the 7 business day window on the original obligation may still be open, which means a same-week fix can often land the money inside the window entirely.
The catch is the watching. A returned contribution that lands in a clearing account nobody reconciles is a shortfall clock running in plain sight. The operational rule the 3-day turnaround makes possible: reconcile fund confirmations and returns within the same week as every pay run. Sent is not received; received is not allocated; only allocated ends the obligation. The weekly three-way check, payroll liability versus clearing house confirmation versus fund allocation, is the entire game, and with the fund side now moving in days, weekly is achievable in a way it never was before.
Use the estimate your super contributions tool to sanity-check liability totals, and keep payroll in Xero configuration clean if that is your platform.
The enforcement pattern the new data supports runs in escalating steps. A mismatch between reported liability and fund receipts is first the raw material for prompts and nudges, ATO correspondence pointing out the gap and inviting correction, the cheapest intervention for a regulator that can see everything. An employer who responds with payment and a voluntary disclosure resolves the incident inside the self-correction machinery, keeps the administrative uplift at or near nil, and stays inside the low-risk posture of the first-year compliance guideline.
An employer who ignores the nudge has converted an automated letter into a compliance case with the evidence already assembled: their own STP feed proving the liability, fund data proving the non-payment, payday by payday. Under the old regime the ATO built SG cases slowly from complaints and records requests. Under the new one, the case file writes itself, and silence is the only remaining ingredient of escalation.
The lesson for operators is not fear; it is sequencing. The system is engineered so that fast, honest correction is nearly free and delay is expensive. Build the rhythm that detects in days, and the reporting regime becomes protective: your own clean data is the evidence that keeps the ATO’s attention elsewhere.
STP shows $14,400 liability for a fortnight; fund data shows $0 received because of a rejected batch. Respond in five days: re-pay, disclose, cost is notional earnings of tens of dollars. Ignore for four months: shortfall, interest, full uplift path, and a record that hurts the next 24 months. Same original error, opposite outcomes.
Assembled, the reporting-era payroll cycle looks like this. Pay run finalised and STP pay event lodged on or before payday, with QE flowing from reviewed pay codes. Super authorised the same day through the clearing channel. Within the week: fund confirmations and any 3-day returns reconciled against the pay run, rejections corrected and resubmitted, anything that slipped past its window repaid and covered by a voluntary disclosure. Monthly: clearing account swept to nil and the GL super liability tied to the STP year-to-date figures. Annually: full reconciliation and finalisation by 14 July.
Nothing in that cycle is sophisticated. All of it is relentless, every payday, no exceptions, which is exactly why it defeats businesses relying on one busy person’s memory and suits a standing finance function built to run it. The reporting regime did not raise the skill bar for payroll compliance. It raised the consistency bar, permanently. For related process design see timely payroll processing and STP phase 2 reporting codes finalisation guide. Onboarding accuracy that feeds clean STP sits partly in people and HR support.
Data wrong, money right: fix via update events so the record matches reality.
Money wrong, data right: pay and disclose; the record already shows the liability.
Both wrong: fix codes go-forward, correct STP history, pay shortfalls, disclose. Do not pick only one track.
What does Single Touch Payroll report under Payday Super?
Each pay event now reports employees’ qualifying earnings and the superannuation liability arising from that payday, alongside the existing salary, wages and withholding data. The ATO matches this liability feed against contribution data reported by super funds to identify shortfalls automatically.
Does the ATO know if I pay super late?
Structurally, yes. Your STP feed states the liability per payday and fund reporting shows what arrived and when, with funds required to allocate or return contributions within 3 business days. Gaps between the two streams surface without any complaint or audit, which is why prompt correction and voluntary disclosure are the only sensible responses to a slip.
What is the 3 business day rule for super funds?
Funds must allocate a received contribution to the member’s account, or return it to the sender, within 3 business days. For employers it means rejections arrive fast, often while the original 7 business day payment window is still open, making same-week fixes possible for anyone reconciling confirmations weekly.
Do I need new payroll software for the reporting changes?
Mainstream STP-enabled payroll platforms carry the Payday Super reporting requirements in their updates. The employer-side work is configuration and rhythm: pay codes correctly mapped to qualifying earnings, pay events lodged on or before payday, and a weekly reconciliation of fund confirmations.
What if the figures in my STP reports are wrong?
Correct them promptly through an update event so year-to-date figures reflect reality. Note the limits: a reporting correction does not move money, and a payment does not fix a wrong report. The remittance and the record are separate obligations, and both must end up true.
When is STP finalisation due?
By 14 July following the end of the financial year. Under Payday Super, treat the pre-finalisation reconciliation, payroll to STP to fund confirmations to general ledger, as the annual audit of the whole super process.
Can fixing my STP data resolve a super shortfall?
No. If contributions in fact missed their window, the shortfall exists regardless of the reporting, and the response is payment plus a voluntary disclosure statement. STP corrections are for making the record accurate, not for making obligations disappear.
What happens first if the ATO’s matching finds a gap?
Typically a prompt or nudge inviting you to review and correct, consistent with the first-year compliance posture in PCG 2026/1. Employers who repay and disclose at that point resolve the matter inside the self-correction machinery; employers who ignore it hand the ATO a case file their own data already wrote.
What is the weekly three-way check?
Payroll liability for the pay run, clearing house or payment confirmation, and fund allocation or return status. All three must line up. Sent is not enough; allocated ends the obligation.
Does late STP lodgement create super shortfall by itself?
Late lodgement is a reporting failure, not automatically a super shortfall, but it breaks the clean record that proves liability and payment align, and patterns of late lodging attract attention. Lodge on or before payday as standard.
